Amplify sensor signals with high precision regardless of temperature changes! Developed zero-drift operational amplifier "LMR1002F-LB"

ROHM Co., Ltd. has developed the zero-drift operational amplifier "LMR1002F-LB" for industrial and consumer equipment, which reduces input offset voltage and input offset voltage temperature drift to extremely low levels.

Since the sensor signal is small, it needs to be amplified by an operational amplifier.
However, if there is an error in the operational amplifier, if you multiply the sensor signal by 1,000 times, the error will also increase by 1,000 times...!

“Ideally, an operational amplifier with an input offset voltage (error voltage) of 0V”

In reality, it is not possible to reduce the error to zero due to characteristics variations and environmental changes, but offset voltage can be automatically corrected.

A "zero-drift operational amplifier" that is as close to zero as possible can amplify sensor signals with high precision.

　
<Features of the new product “LMR1002F-LB”>
1. Input offset voltage is suppressed to a maximum of 9µV, 94% less than conventional products!
This eliminates the need for peripheral parts required for correction, contributing to reductions in design man-hours and costs.

2. Achieves the smallest input offset voltage temperature drift in ROHM operational amplifier history!
​Sensor signals can be amplified accurately regardless of environmental changes such as temperature.

Ideal for first-stage amplifiers that amplify minute voltages for sensor output and current detection in industrial equipment, such as temperature, pressure, and flow rate measuring instrument sense amplifiers and power control inverter current detection amplifiers.
